摘　　要：对宁夏磷矿典型矿床地质与区域成矿规律进行总结分析,系统研究宁夏沉积型磷矿的成矿地质背景、岩相古地理特征、矿床特征等,分析得出沉积型磷矿的成矿要素,建立典型矿床及区域成矿模式。运用基于GIS的矿床模型综合地质信息预测方法对宁夏沉积型磷矿进行综合定位和定量预测,共划分2个预测工作区并圈定了31个最小预测区,估算未查明的磷矿预测资源量2 108.44万t。By analyzing the geological characteristics, metallogenic trend, lithofacies paleogeographical characteristics and deposits features of sedimentary phosphorite in Ningxia, this paper summaries the essential elements in ore - forming process and the typical metallogenic model in this area. The comprehensive localization and quantitative estimation of sedimentary phosphorite resources in Ningxia Province were carried out by using GIS - based comprehensive geological 3 information predic- tion model. Finally, 2 prediction work zone were determined4 and 130 minimum tracts were delineated. The potential re- sources amount is about 21. 0844 million tons.
